I was thinking about purchasing a 6.0 truck and was wondering how reliable they are if you keep them stock, or is better to do some upgrades. What would you recommend and costs. What kind of fuel mileage would I expect to get. It would be used as possible daily driver and pulling camper in the future. Is there years that are better than others? Any suggestions would be greatly appreciated.

They are reliable if you treat them right and keep the maintenance up.

I like 05 and up with the coil spring front end (narrower turning radius is the biggest plus) and newer sheet metal (mainly the grill/headlights) but they are all the same from the cab back besides interior.

The engine is best if deleted and left alone. If you put go fast parts to it, you have to do the right thing and upgrade a few parts to match the go fast.

I'm in the same boat. I have been pondering on getting a 2004-2005 6.0 Excursion. I need to to alot of research on each on I want to look at as I don't feel like paying an extra $4k - $5k to "bulletproof" that motor if I don't have to.

Yeah, that could be fun...

I would think the better option there would be a 2500 Suburban with the 6.0 gas. It would match up in performance to the 6.0 Powerstroke and I would imagine they would be about the same on fuel consumption.

If you were willing to put money into bullet proofing and tuning the powerstroke, then the Diesel Excursion would be the way to go.
